Answer:
A. x = 2y
64x + 132y = 1040
B. adult ticket = $8
student ticket = $4
Step-by-step explanation:
x = adult ticket
y = student ticket
A. an adult ticket is 2 times a student ticket, therefore, x = 2y
64(price of adult ticket) + 132(price of student ticket) = 1040
B. to find the price of each ticket, find the price of the student ticket (y) first since you have the adult ticket (x) by itself. Now you can substitute x = 2y into 64(x) + 132(y) = 1040. So you would get 128(y) + 132(y) = 1040. Next, combine both y to get 260(y) = 1040. Then divide both sides by 240 to get y which equals $4. Then you can easily find x which would equal $8
